Investigation of a novel elastic-mechanical wheel transmission under light duty conditions
No full textA novel 'Elastic Engagement and Friction Coupled' (EEFC) mechanical transmission has been proposed recently in which the power is transmitted through elastic tines on the surfaces of the driving and driven wheels. This study introduces new variations of EEFC mechanical wheel transmission ( broadly emulating a gear-pair) with small contact areas for use under light duty conditions. Because a drive of this type inevitably has a strong statistical component, theoretical analysis of the geometrical and mechanical relationships has been attempted by using linear modeling and empirical weightings. Several simple forms of the EEFC wheel transmission are tested under limiting ( slip) conditions for transmission force and transmission coefficients against normal load. Normalized standard deviation of these parameters is used to summarize noise performance. Models and experiments are in reasonable agreement, suggesting that the model parameters reflect important design considerations. EEFC transmissions appear well suited to force regimes of a few tenths of a newton and to have potential for use in, for example, millimetre-scale robots

Phylogenetic relationships among the colobine monkeys revisited: new insights from analyses of complete mt genomes and 44 nuclear non-coding markers.
No full textPhylogenetic relationships among Asian and African colobine genera have been disputed and are not yet well established. In the present study, we revisit the contentious relationships within the Asian and African Colobinae by analyzing 44 nuclear non-coding genes (>23 kb) and mitochondrial (mt) genome sequences from 14 colobine and 4 non-colobine primates.The combined nuclear gene and the mt genome as well as the combined nuclear and mt gene analyses yielded different phylogenetic relationships among colobine genera with the exception of a monophyletic 'odd-nosed' group consisting of Rhinopithecus, Pygathrix and Nasalis, and a monophyletic African group consisting of Colobus and Piliocolobus. The combined nuclear data analyses supported a sister-grouping between Semnopithecus and Trachypithecus, and between Presbytis and the odd-nosed monkey group, as well as a sister-taxon association of Pygathrix and Rhinopithecus within the odd-nosed monkey group. In contrast, mt genome data analyses revealed that Semnopithecus diverged earliest among the Asian colobines and that the odd-nosed monkey group is sister to a Presbytis and Trachypithecus clade, as well as a close association of Pygathrix with Nasalis. The relationships among these genera inferred from the analyses of combined nuclear and mt genes, however, varied with the tree-building methods used. Another remarkable finding of the present study is that all of our analyses rejected the recently proposed African colobine paraphyly and hybridization hypothesis and supported reciprocal monophyly of the African and Asian groups.The phylogenetic utility of large-scale new non-coding genes was assessed using the Colobinae as a model, We found that these markers were useful for distinguishing nodes resulting from rapid radiation episodes such as the Asian colobine radiation. None of these markers here have previously been used for colobine phylogenetic reconstruction, increasing the spectrum of molecular markers available to mammalian systematics

Native p-type transparent conductive CuI via intrinsic defects
No full textThe ability of CuI to be doped p-type via the introduction of native defects has been investigated using first-principles pseudopotential calculations based on density functional theory. The Cu vacancy has a lower formation energy than any of the other native defects, which include I vacancy (V(I)), Cu interstitial (Cu(i)), I interstitial (I(i)), Cu antisite (Cu(I)), and I antisite (I(Cu)). Combined with its shallow acceptor level, it offers sufficient hole concentrations in CuI. The natural band alignments as compared to zinc-blende ZnS, ZnSe, and ZnTe have also been calculated in order to further identify the p-type dopability of CuI. It is found that CuI has a relatively high valence band maximum and conduction band minimum, which also makes it easy to dope CuI p-type in terms of the doping limit rule. In addition, the small effective mass of the light hole-about 0.303m(0)-can provide high mobility and p-type conductivity in CuI. All of these results make CuI an ideal candidate for native p-type materials (C) 2011 American Institute of Physics. [doi:10.1063/1.3633220

Rewriting of Jin Ping Mei in English : eroticism or exoticism
No full textJin Ping Mei, the greatest masterwork of Ming novels, continues to be mired in genre
classification disputes even today. The banning of the novel in China since the early Qing
Dynasty is attributable to its classification as an erotic novel. To most literati and academics,
it is not an erotica. Acclamation by Lu Xun that it is the most famous of the novels of manners
bears such testimony. Internationally and in China, academic conferences on JPM are held
regularly, the most recent of which was the 12th International Academic Conference on JPM
held at Jinan University in October last year. In the West, Jing Ping Mei is held in high regard
by academics such as Clement Egerton and David Tod Roy. Their rewritings, half a century
apart of each other, happened to straddle the sexual revolution in the 1960s, which divided the
ideology, poetics and patronage collective into two distinct eras.
Roy’s initial attraction to JPM was its reputation of being pornographic but his studies led
him to believe it is both a masterwork of Chinese literature and world literature. His skopos is
to convey the real China to Americans through his rewriting of JPM, a novel that chronicles
the quotidian lives, history and culture of the Chinese people. Roy’s complete rewriting without
omitting any of the ST has become an encyclopaedia for researchers around the world today.
On the other hand, Egerton’s skopos is anthropological in nature, which led him to omit
irrelevant Chinese elements in his rewriting. Constrained by the ideology and poetics imposed
on the patronage in his time, he allowed his rewriting to be subjected to literary censorship in
the form of manipulation by Latinisation. Statistics has shown that the number of expurgated
words is a mere 1.3%, or a miniscule fraction of one percent if we were to only count the
objectionable words. As established sinologists, Egerton and Roy would be aware of this
proportion. Therefore, based on their rewritings, should JPM be regarded as an erotic novel, or
is it in fact an exotic novel?
This thesis sets out to explore the theoretical foundation in the rewriting of JPM, the skopos
of each of the rewriters as well as the ideology, poetics and patronage that might have
constrained rewriters such as Egerton and Roy, whose skopoi and rewritings have elucidated
the exoticism of the novel in many ways. Skopos and rewriting are mutually complementary.
Products are purpose-driven. Without skopos, there would not be a purpose-driven rewriting.
The holistic study of skopos and rewriting would lend authority, credibility and practicality to
the existence of rewritings, as well as the applicability and relevance of these rewritings in the
target society and culture. The mutual complementariness of skopos and rewriting applies
similarly to all literary translations (or rewritings) and the study of these twin factors serves to
systemise literature review, rationalise its reception and acceptance, and lay the foundation for
other rewriters wishing to embark on a literary translation.

Genetic variation in nine Shorea species (Dipterocarpaceae) in Indonesia revealed by AFLPs
No full textShorea is the largest and most important genus of the Dipterocarpaceae. The genetic diversity and structure of nine Shorea species from two different locations, namely Nanjak Makmur in Sumatra and Sumalindo in Borneo, were evaluated using amplified fragment length polymorphism (AFLP) markers. A total of 274 trees were investigated at 85 polymorphic AFLP loci. Levels of genetic diversity of these species ranged from (H) over bar (e)=0.100 for S. acuminata to (H) over bar (e)=0.165 for S. blumutensis. The population of rare species S. blumutensis possessed the highest genetic diversity suggesting that geographically restricted species can have levels of genetic variation comparable to closely related widespread common congeners. Analyses of molecular variance revealed that the genetic variation was mainly found among species in both locations (57.7% in Sumatra; 56.3% in Borneo). The unweighted pairgroup method using arithmetic averages dendrogram of all samples revealed an almost complete separation of species. Thus, AFLP markers proved appropriate for phylogenetic studies of Shorea species. Specific markers have been detected showing high-frequency differences among species and between regions within species. Sequence information of these markers can be used to develop specific polymerase chain reaction markers for wood identification. The possibility of interspecific hybridization was discussed
